I08 AGARICUS. 



Collybia. sembling in habit some Psathyra or Panceolus, but the spores are absolutely 

 colourless when fully mature. 



On the ground. Epping Forest, 1880. Oct. 



Name Psathyra-like. Cooke Grevillea, vol. xi. p. 155. Illust. PI. 266. 



220. A. xanthopus Fr. Pileus 2.5-5 cent - ( : ~ 2 m -) broad, tan 

 then becoming pale, slightly fleshy, campanulato- convex then 

 expanded, lax, umbonate, smooth, dry, margin at length spread- 

 ing, slightly striate. Stem 7.5 cent. (3 in.) and more long, 4 mm. 

 (2 lin.) and more thick, tough, fistulose, equal, even, smooth, 

 yellow-tawny, strigosely rooted at the base. Gills truncate behind, 

 at first adnexed, soon free, crowded, very broad, lax, whitish. 



Allied to A. dryophilus, from the common form of which it may be safely 

 distinguished by its umbo, by its broad lax gills, and by the base of the stem. 



On stumps and among leaves. Uncommon. July.

221. A. nitellinus Fr. Pileus 2.5-4 cent. (i-i> in.) broad, 

 when moist tawny or brick-tawny, when dry somewhat tan, some- 

 what membranaceous, convexo-plane, obtuse, smooth, polished, 

 but when more accurately examined somewhat riigulose, pellucido- 

 striate when moist ; flesh of the same colour. Stem 7.5 cent. (3 

 in.) long, 3 mm. (\% lin.) thick, appearing cartilaginous from its 

 rigidity and polished surface, but at length soft, and readily 

 splitting into fibrils, stuffed then fistulose, equal, flexuous, some- 

 what rooted, smooth, slightly striate, ferruginous-tawny, yellow 

 when dry, often white villous at the base, more rarely obsoletely 

 pruinose at the apex. Gills adnate, very obtuse behind and equally 

 attenuated in front, somewhat crowded, narrow, whitish. 



There is a smaller variety with the pileus 12 mm. (% in.) broad, umbonate, 

 and the stem scarcely 2.5 cent, (i in.) long. Solitary or gregarious, inodorous. 

 From its having the habit of A. laccatus, and the stem internally fibrous, it 

 approaches Clitocybcc, to which it was formerly referred, but from its polished 

 shining stem it is better referred to Collybia.

222. A. succineus Fr. Pileus 2.5 cent, (i in.) broad, rufous or
